Rock Band 3 Enhanced - Wii/PS3 Crossplay

This has been perhaps my biggest long-term goal since starting the RB3 Enhanced project a few years ago. Crossplay is one of those things that would have been great to have as an official feature in RB3, but never happened (nor was there probably ever a chance it could happen even if Harmonix wanted it, crossplay was unheard of in those days). With a lot of work and heavy reverse engineering, it has finally been achieved. For anyone interested in a high level overview of the technical details, basically I am fixing up the incoming and outgoing packets on the Wii side so that the Wii uses the PS3's protocol, while not modifying the PS3 version or much of the networking code at all. Some PS3 packets contain platform-specific bits (such as the NPID), while the Wii has Wii platform-specific bits, so I have to essentially skip over them when parsing incoming PS3 packets on Wii, and write "good enough" fake data when sending outgoing Wii packets to PS3. The networking protocols on RB3Wii and RB3PS3 are extremely similar, so after fixing those troublesome packets it just (mostly) works. There are still some issues with this so it won't be released quite yet. For one, the PS3 can not host - it will crash when the Wii joins. Second, as seen in the video, there is a significant delay because the Wii doesn't play the intro that the other consoles do. Both of these issues are fixable and I don't expect there to be any real showstopping issues beyond these. I have verified that DLC, customs, and exports work, as long as both versions are playing the same MIDI file, there is no issue. Up next, getting Xbox 360/Wii/PS3 crossplay working...360 is a completely different beast and there are much more significant changes to the networking protocols, but I am very confident it can be done.
